Atelerix

Atelerix is a genus of hedgehogs in the family Erinaceidae, comprising several African species known for their spines and nocturnal habits. Members of Atelerix are typically small to medium-sized hedgehogs with brown or gray dorsal quills, a lighter underbelly, and short tails. Like other hedgehogs, they defend themselves by curling into a tight ball with spines outward.

Geographic range and habitat: Species occur across much of Africa, from North Africa through sub-Saharan regions to southern Africa. They inhabit savannas, grasslands, woodlands, and agricultural areas, often avoiding dense forests or deserts.

Behavior and diet: They are generally solitary and nocturnal, foraging on insects, worms, other invertebrates, fruit, and plant matter. They are adaptable to various habitats and may burrow or seek shelter in brush or debris. In colder climates some may enter torpor or hibernate for part of the year.

Species: Recognized members include Atelerix algirus (North African hedgehog), Atelerix albiventris (African pygmy hedgehog), Atelerix frontalis (Southern African hedgehog), and Atelerix sclateri (Sclater's hedgehog). Atelerix albiventris is the best known in captivity and is commonly kept as an exotic pet in many regions.

Reproduction and longevity: Mating can occur in a variety of seasons depending on the climate. Gestation is roughly a month, with litters typically consisting of several young. In the wild, lifespans vary and are influenced by environmental conditions; in captivity they can live several years with proper care.

Conservation: The conservation status varies by species, with most listed as Least Concern or Data Deficient. Local populations may face threats from habitat loss and human disturbance, but the genus as a whole remains relatively widespread in suitable habitats.
